Full disclosure: I was given a prototype by PEIN Gear to test although I did pay for shipping and customs
The PeinGear Pedal mount is a device that is meant to keep your pedals at a set distance from your chair as well as tilt the pedals to a more comfortable angle. It's a rather basic powder coated steel design but it does it's job very well.
My prototype mount didn't come with any fancy packaging but it did have a manual which was perfectly adequate in helping me assemble it. I would likely have been able to figure it out myself since it's not difficult at all. The package was extremely compact and weighed something like 3.5 kg.
Assembling the mount was easy and adjusting it for my taste was straight forward. There aren't any quick latches or similar, just standard bolts that you fasten with the included allen key. Apparently my prototype is slightly different than the finished product but in most cases my opinions here should hold true to the finished model as well. I didn't get any floor protector pads but PEIN assures me that such things will likely be included in the final product.
I have tried the mounts mostly with my MFG Crosswinds but as far as I can tell these things will likely fit most pedals on the market and if they don't then anyone with a modicum of DIY skills should be able to figure something out. The crossbars for mounting pedals are very configurable and can be put in almost any position.
The mounts works exactly as advertised and they are very sturdy when assembled. Once the chair is in the U-profile the pedals will not move, neither forwards, backwards nor sideways. The angle adjustment works just as it's supposed to and while perhaps making flight pedal use slightly less realistic it can help a lot with comfort after long hours of play, depending on pedal type and game of course. The mount works just as well without the angle adjustment.
The mount doesn't take up a lot of space and the bar connecting to the chair can be folded up which reduces the footprint considerably when stowed. When fully disassembled it's extremely compact.
I can't really find anything to fault with the pedal mount, it is exactly what it looks like and it does what it's supposed to. If you need your pedals to stay put and feel that the price point is reasonable then you should absolutely think about it. My only gripe is that getting the chair into the U-profile is a bit unwieldy and can't be done while sitting in the chair. For my setup this means that getting myself in position between the monstertech mounts while the chair is locked to the pedal mount makes me consider losing a bit of weight. This isn't technically a failing of the pedal mount, though, but PEIN Gear should absolutely look into some kind of quick release if they want me to throw more money at them.
This mount has solved a problem I've struggled with ever since I bought my MFGs. With the mount the pedals finally perform the way they were meant to, they don't move and they don't tip over. I can push the pedals as hard as I like and they will stay put. If I hadn't been given this prototyp I'm very much certain I would have bought them if the price was anywhere near reasonable (as of writing this I have really no idea what PeinGear is planning on charging for them). This is of course from a guy that has dual monstertech mounts and a lot more joysticks than arms. I haven't seen any other product like this on the market though. It's a great product and my dealings with the PEIN Gear company has been excellent.
